Here is what TS-Doctor developer answered on NMT forums
------
the PSCPrefix error is not a big problem because this error is only at the
beginning of the stream. This error shows that the header of some PES
packets
are not starting with the right value, so that every of this not compliant
packets are ignored (discarded).
The video_full_range_flags lines are only for debugging if there are
problems
with the flag. You can ignore them because they are not marked as errors or
warnings!

I think this is a good quess. I don't know how much PCH reads the stream for
PMT table (first 10kB, first 100kB,...?), so if it does not have it in time
it quits the stream.
So could streamdev be easily modified to provide PMT at stream start? And
could PMT be rewritten later if new streams are found. With this I mean on
first PMT you have audio/video-stream. And subtitle appears 60 seconds from
the start so give new PMT with private subtitles streams as well?

How about the other symptom I was giving output. My VDR machine and its
mplayer. Sometimes it recognizes stream as MPEG-2, and sometimes H.264. What
do you believe, problem with TS stream or problem with Mplayer stream
recognition.
What is the best linux tool to diagnoze problems on TS? TS-Doctor is windows
software and does not run under terminal emulator.

I don't believe this is problem, as not all shows have subtitles. But
they could have empty packets submitted?

I need to check this one when I have access..
